Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-14303/ (Markdown: https://insights.sbomify.com/MAL-2026-14303/index.md)","id":"MAL-2026-14303","markdown":"https://insights.sbomify.com/MAL-2026-14303/index.md","name":"MAL-2026-14303","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Package x6842179305 ships a main entry (1.js) that invokes the `Function` constructor over a custom-encoded, keyed/XOR-decoded byte buffer, causing an opaque payload to execute whenever the module is required or imported. A sibling file (ui.js) contains a matching custom-alphabet decoder feeding another opaque byte stream. The runtime behavior of the decoded payload — including any network destinations, credential access, or filesystem writes — is not statically determinable because the code has no readable source form. The package name is a numeric burner-style identifier with no documented purpose, no README describing functionality, and no legitimate library shape (no exported API surface, no source tree). A Function()-constructor executor over a custom-encoded byte table on module load has no benign engineering rationale and matches the obfuscated-loader / dropper pattern used to hide install- or import-time payloads from static review.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in x6842179305 (npm)","id":"MAL-2026-14303","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"x6842179305","purl":"pkg:npm/x6842179305","source":"MAL-2026-14303"}],"products":null,"published":"2026-08-19","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-14303/"}
